Esophagogastric ring; Schatzki's ringDefinition Return to top
A lower esophageal ring is an abnormal ring of tissue located at the junction of the esophagus (the tube from the mouth to the stomach) and the stomach, which can cause swallowing problems.Causes, incidence, and risk factors Return to top
Physicians disagree on the cause of this disorder, unless it obviously follows ingestion of caustic material such as lye or strong acids. It may be a congenital defect (present from before birth). Alternatively, it may be related to chronic injury caused by gastroesophageal reflux disease (GERD), in which stomach acid leaks into the esophagus and irritates it.
Esophageal rings are known to occur from drinking a caustic substance, causing scar tissue. The condition may produce swallowing difficulties.
Symptoms Return to top
Signs and tests Return to top
Tests that show the lower esophageal ring include:Treatment Return to top
Initial treatment typically consists of dilating (stretching) the ring by passing a dilator or balloon through the ring. Any associated reflux should also be treated. Surgical cutting (excision) of the ring may be necessary if dilation is unsuccessful.
Expectations (prognosis) Return to top
It is possible that the difficulty swallowing may return, and repeat dilation may be necessary.
Complications Return to top
There are usually no complications except for the noted difficulty swallowing and chest pain.
Calling your health care provider Return to top
Call for an appointment with your health care provider if symptoms suggestive of this disorder develop, to rule out other causes of the symptoms and to determine the best treatment for you.
